Edible weeds

After listening to the Food Summit from Ashevillage we began to wonder what "weeds" we have in our yard/garden that we can eat.  The Food Summit suggested getting to "know" 5 edible weeds well. We are focusing on these five.
Our friend introduced us to purslene and we love it in our salads. We found dandelion, curly dock, plantain leaves, and chickweed in our gardens. As we are weeding to plant our summer garden, we are adding these "weeds" to our salad mixes. The herbfairies link has child friendly recipes.

We found a couple of links for weed identification.
